Fixed Cycles: Contour Pocket with Contour Formula
9.1 SL cycles with complex contour formula

Selecting a program with contour definitions

With the SEL CONTOUR function you select a program with contour
definitions, from which the TNC takes the contour descriptions:
Show the soft-key row with special functions
Menu for functions: Press the soft key for contour
and point machining
Press the SEL CONTOUR soft key.
Enter the full name of the program with the
contour definitions and confirm with the END key.
Program a SEL CONTOUR block before the SL
cycles. Cycle 14 CONTOUR GEOMETRY is no longer
necessary if you use SEL CONTOUR.

Defining contour descriptions

With the DECLARE CONTOUR function you enter in a program
the path for programs from which the TNC draws the contour
descriptions. In addition, you can select a separate depth for this
contour description (FCL 2 function):
Show the soft-key row with special functions
Menu for functions: Press the soft key for contour
and point machining
Press the DECLARE CONTOUR soft key.
Enter the number for the contour designator QC,
and confirm with the ENT key
Enter the full name of the program with the
contour descriptions and confirm with the END
key, or if desired,
Define a separate depth for the selected contour
With the entered contour designators QC you can
include the various contours in the contour formula.
If you program separate depths for contours, then
you must assign a depth to all subcontours (assign
the depth 0 if necessary).
